Letus Extreme Questions

[iconoclast6]

Hi Folks...

Have browsed the forum for narratives on Extreme user experiences, but haven't seen this addressed, so ...

Have followed the setup steps and definitely see the SLR lens effect. Doesn't seem to need as much light as my buddy's RR. I can see some DOF, however, I do not see any appreciable difference with the adapter turned on or off.

I am using a DVX100b shooting in 24P with no outrageous scene settings, with 50MM, f1.4 and f1.8 lenses. When I focus on the object, it looks more grainy and soft than sharp. The object comes into focus, but its not sharp at all. The lens brings the object into focus within a very small range of travel, probably about 1/8". My SLR lens is set to 1.4 or 1.8, and am using no ND filter.

This does not change whether I change my camera focus or not. Further when I pull the way back..I notice that the GG is not not perfectly centered when I zoom all the way out. When I zoom all the way out, in camera, I can see past the GG..and I notice that the GG is alligned more on the right than in the middle of the focal tunnel. Is this normal?

I view the image in the camera LCD as well as a large screen monitor.

In any event, I am expecting to see some difference with the Extreme on, as well as a sharper image...anyone have any advice here? I posted a similar question at the Letus forum as well. Thus far, I am not retreating back to my edit bay...but I hope the Extreme is ok, and I'm simply doing something wrong...

Thanks for any thoughs

Turning on the Extreme shouldn't affect sharpness, but it will make the grains go away. The image is soft because the lense is wide open, you need to stop down to f4 or more.

The Letus GG is centered but the camera is not. See here my questions for a workaround (none yet):

Im thinking of building my own thread ring with horisontal compensation. But i Letus is aware of this and hopefully they will offer a solution to this as well at some point.

No need to shoot progressive with the LEX if you don't want the strobing effect when panning.. Using a DOF adapter it makes not difference to the pic if you shoot Progressive or Interlaced

you're kidding, right?

[Slinkii]

What do you mean by what?

[TheMacB]

that when you're using an adapter it doesn't make a difference if you shoot progressive or interlaced.

if you shoot interlaced you're going to have interlaced footage. right?

[thekreative]

you shoot interlaced and you get interlaced........so video interlaced with great DOF
so go with progressive.

[Slinkii]

I'm talking about the overall look of the footage, obviously if you shoot interlaced the footage format will still be interlaced.

[Slinkii]

Ok so shoot progressive if everyone says to.. The advantage I see for someone using a DVX which doesn't have a whole range of frame rates is when you shoot interlaced you can load it in your NLE system with a progressive workflow, change the playback speed and you get real nice slow motion.. Shooting progressive eliminates that option and when you have a DOF adapter on the front, the difference between progressive and interlaced doesn't instantly jump out at you anymore...

[TheMacB]

you're right, 60i looks better with the adapter than without but the cadence is what gives it away. but the "overall look of the footage" will be much more videoish- you'll see it in the movement.

if you're going for slow-mo and can't overcrank, then yeah, interlaced might be best (you're going to lose a whole lot of resolution). but an adapter is not going to disguise the cadence of 60 interlaced fields.

[Slinkii]

I agree with you TheMacB but my original post said something in the order of
"If you don't want the strobing motion effect attached to progressive then shoot interlaced"

[TheMacB]

my bad, you're right about that. i was just thrown by this sentence:

"Using a DOF adapter it makes not difference to the pic if you shoot Progressive or Interlaced."

because it makes a big difference.

regarding: I am using a DVX100b shooting in 24P with no outrageous scene settings, with 50MM, f1.4 and f1.8 lenses. When I focus on the object, it looks more grainy and soft than sharp. The object comes into focus, but its not sharp at all. The lens brings the object into focus within a very small range of travel, probably about 1/8". My SLR lens is set to 1.4 or 1.8, and am using no ND filter....

so I'll try stopping down to f4 to attain a sharper look. I guess good points have been made: is there a real benefit to shooting (with the DVX100b) in 24p if the adapter is being used, or should interalaced be used? I'd rather not deal with issue in post, hence the adapter, but I also will try to get the sharpest look possible....

More on this when I get back on it...
